ARC was recently given a set of 78 Instantaneous Recordings (acetates / lacquers) of Roosevelt's presidential acceptance speech at the Democratic convention, Chicago, 7.2.1932. A long winded set of 8 aluminum discs. Real NY history I think. Would have been cut in situ - scarce, if not rare. This set made by NBC Radio - I’m sure other companies made live recordings also and I have seen excerpts on film. Anyone know anything about this?
